FEA Gurus,
I have a Cylindrical Ring (solid45) on which I need to put a Sheet (shell63).
I want to lay the Sheet on the cylindrical outer surface of the Cylindrical Ring in segments or say in stages of say 20 degrees (I have 2 of such segments for now, later I may have more of these segments laid on the ring).
It is going to be a contact analysis because I have friction between the surfaces. Thus I need to have contact pairs between the out side surfaces of the Cylindrical Ring and the inside surfaces of the Sheet. I need to apply a cylindrical tension force (in theta direction) which I apply by resolving force in X and Y direction in Cartesian system. (I know I can rotate the nodal coordinate system and apply force in theta direction however for now I think that is not the concern).
Finally this is what I do-
I build the Cylindrical Ring and mesh it.
I start with 1st segment of 20 degrees. I create it, mesh it, and make a contact pair between this and the Cylindrical Ring.
It solves pretty good (this is my 1st load step).
Then I create 2nd segment and mesh it by going into prep7
However for this 2nd segment I can’t create the contact pair. I get a message “No surface elements were generated”.
Thus I can’t go ahead and solve for second load step because I don’t have the contact pair between Cylindrical Ring and Sheet surfaces.
Note on what I have tried different - Even if I don’t solve (comment with !) for 1st load step. ANSYS doesn’t create contact pair for my 2nd segment. I have tried to make the area for the secong segment with key points instead of extruding like in this code. Neither worked for me.
Could any of you please let me know what I am doing wrong here and what I can do to fix it? Code is here.
Regards,
-HMT
